What is the difference between anxiety and anxiety disorders?

A

Remember, there is no clear line between “normal” anxiety and anxiety disorders. They differ in the extent of symptoms and duration.

factors and environmental influences in childhood.”.

Good history and MSE exclude treatable depressive illness.

General measures;

27
Q

What is the Epidemiology of PTSD?

A
  • Much of the population data comes from the USA
  • Variable cultural factors and exposure to disaster lead to variable prevalence, 1-4% one-year prevalence
  • Women sufferers out number men 2 to 1 in USA
28
Q

What are the causes of PTSD?

A

Main cause - Nature of stressor

A life-threatening and degree of exposure generally confers greater risk however

Vulnerability factors;
- Mood disorder
- Previous trauma especially as a child
- Lack of social support
- Female
- Protective factors (examples)
- Higher education and social group
- Good paternal relationship

Susceptibility partly genetic

29
Q

How is PTSD managed?

A
  • Survivors of disasters screened at one month
  • Mild symptoms “watchful waiting” and review further month
  • Trauma-focused CBT if more severe symptoms
  • Eye Movement Desensitisation and Reprocessing (In moment adrenaline is going and not processing information and what is going on. Partly to do with how memories are made with rapid eye movement when sleeping etc)
  • Risk of dependence with any sedatives but patient may prefer medication SSRI or TCA (Can worsen if given too soon)

*Avoid alcohol and speaking to people helps

*Mirtazapine helps with flashbacks and is a sedative helping to sleep
